3,187,618 ORGAN PRE-SET Joseph A. Hohes, Falls Church, Va, ass-'sanar toScope, Inc., Falls Church, Va., a corporation of New Hampshire FiledNov. 2t), 1962, Ser. No. 238,947 Claims. (Cl. Sti-Sill) The presentinvention relates generally to electronic organ pre-set mechanisms andmore particularly to an organ pre-set mechanism in which a single buttonselectively controls which of a plurality of the organ instrumentationsare attained and wherein certain tone colors normally expected with aparticular instrumentation are selectively removed or tone colors notexpected can be selectively added.

In the past, single button organ preset mechanisms have been designedbut have generally not provided the organist with suicient liexibilityin determining which tone colors are to be played with the selectedinstrumentattion. Thus, once it has been decided that theinstrumentation is to be a cathedral organ, a theater organ, or acalliope, etc. the tone colors (organ footages) are invariablydetermined.

In the organ of the present invention, the organist, in addition tobeing able to select. the instrumentation with a single button, is ableto subtract or add and subtract and add certain tone colors normallyassociated with the particular instrumentation. This is achieved with arelatively simple mechanical mechanism that controls the selection otmusical tone generators.

The mechanism includes a plurality ot stacked bars which by principle ofa parallel bar linkage selectively engage and activate a multiplicity ofcards, one card being provided for a plurality of predetermined musicaltones. Connected to each card is at least one switch for permittingenergization of a selected musical tone generator when a key is struck.Similarly positioned switches on selected cards are ganged together sothat tone generators associated with a number ot keys may be energizedby activation of a single card. The bars and ganged switches arearranged to provide activation of at least one tone generator inresponse to each key being struck. To control card activation, each barincludes a plurality of tabs Which engage instrumentation selectionbuttons on the organ. Activation of each instrumentation selectionbutton results in translation of predetermined bars in accordance withthe desired musical result. Each bar includes a further plurality oftabs which activate selected cards to a position which enables theelectric tone generator circuits to be established in response to organkey activation.

To select which tone colors normally associated with an instrumentationare to be removed, a plurality of pivotable, manually operated tilttablets, one for each tone color foot, is provided.v Each tilt tablet isconnected to a separate circuit actuating card. When a tilt tablet isdepressed to remove a particular footage trom the arrangement, the cardwith which it is connected is returned to its unactivated position sothat all of the tone generator switches controlled by the particularcard, including those ganged to the card switch, cannot be closed when akey is struck during organ operation. Hence certain tonesnormallyassociated with the instrumentation are removed. The other cardsactivated by the selected instrumentation 3,187,613 Patented June 8,1965 control bar are not affected by the ensuing return of the selectedcard to its unactivated position because no permanent card and barconnection is provided. Tone colors can also be added by depressing atilt tablet not activated by the instrumentation Selection button in theopposite direction than that for tone removel. Thereby, energization ofthe tone generator switches controlled by the card coupled to thedepressed tablet is eiected when the appropriate keys are struck.

To return all of the cards to their unactivated position when it isdesired to change the instrumentation, each card is provided with anaperture through which a furtherbar is inserted. This bar is normallypositioned so that the cards can travel the necessary distance to permitcircuit activation. When it is desired to change the type of organinstrumentation, this bar is translated so that it engages the edges ofthe apertures closest to the other bars and returns all ot the cards totheir initial location.

To permit ease of bar movement by the tilt tablets and the organinstrumentation buttons, the former are provided with over centersprings which maintain the respective cards in their activated positioneven though the contact bar is Withdrawn. As a result, theinstrumentation buttons are returned to their unactivatedposition once aselection is made and thereby obviating the need for a button lockingmechanism and permitting ilexibility and simplicity in removing tonecolors.

Because of the relatively great distances between the ten differentarrangement selection buttons of the present organ and the need formoving each of the cards a like distance no matter which of the tabs onthe several bars engage them, it has been found necessary to developwhat We believe to be a novel mechanical activating mechanism. By thismechanism, card translation in a single direction is obtained by movingeach of tne activating bars to produce a resultant force which hascomponents orthogonal and parallel to the direction of card movement.This is accomplished With a pair of parallel pivot arms, one 0f which isrotatably mounted at each end of the bars at the edge proximate thecards. On the other edge, at points slightly toward the center of thebar from the pivot arms, a pair of parallel extending extension springarepositioned. When a force is applied orthogonally to the longitudinalaxis of the bar between the points Where the pivot arms are located byan instrument selection button, the bar is translated at an angle, otherthan a right angle to the bar longitudinal axis, which depends on theangle subtended by the longitudinal axis, and the pivot arms. When the`force is removed, the bar returns to its initial location due to theparallel forces exerted by the extension springs. To control cardmovement in a direction orthogto the longitudinal axis of the bardespite the nonorthogonal bar movement, each card rides in guide slotsand is connected to a rigid bar, both of which are properly orientatedto achieve the desired card movement. Since the cards and theiractuating tabs are located at different positions relative to the barlongitudinal axis when the cards are in the activated and unactivatedconditions, the tabs must be of sutcient width to engage the cardsthroughout the limits of the bar movement. By this mechanism it ispossible to translate each of the cards, no matter what its locationalong the bar, by a like distance in response to activation or theywidely separated instrumentation buttons.

It is, accordingly, an object of theV present invention to provide a newand improved organ preset mechanism.

It is another object of the present invention to'provide a new andimproved organ preset mechanism in which a select-ion from one of aplurality of organ arrangements is possible with a single mechanismactivated by the organist.

An additional object of the present invention is to provide an organpreset mechanism in which a selection from one of a plurality otorganarrangements is possible with a single mechanism activated by theorganist and in which tone colors normally yassociated with thearrangement can be selectively removed or added.

A further object of the present invention is to provide a new andimproved organ preset mechanism in .which a lmultiplicity of presetbuttons at relatively diverse distances from each other translate asingle mechanical activating bar at the same angle by a like distance.

Yet an additional object of the present invention is to provide a single.button organ preset mechanism which permits selective tone colorremoval or addition, or removal and addition, hence tone selectionexibility, with ease by the organist.

Still an additional object of the present invention is to provide anorgan preset mechanism which is relatively inexpensive,requires-virtually no maintenance, and is subject to long continuous usewithout the need for replacement.

The above and still further objects, features and advantages orf thepresent invention will become apparent upon consideration of thefollowing detailed description of one speciiic embodiment thereof,especially when taken in conjunction with the accompanying drawings,wherein:

Reference is now made to FIGURES 1 and 2 of the drawings which areillustrations of the top and front view, respectively, of the keyboardmechanism of the present inventiomwherein an upper or main organ manualIVI and a lower or accompanying organ manual 12 n are provided.Positioned on the bezel surface 213 directly Positioned on surface 15 orbezel surface 13 are four sets Zut-Z4 of tilt tablets 17. Tilt tabletsets 2l, 22, and 23 are positioned on the right side of surface I6directly above upper manual III while tilt tablet 24 is positionedgenerally above the lower manual 112.y Tilt tablet sets 21 and 22.control the voices and effects, eg. diapason, llute, string, horn,sustain, percussion, selected for the upper manual I1 and set 23controls the tone color ootages for the upper manual. The tilt tabletsI7 of set 2d control which of the diapason, llute, string, `or hornvoices of the accompanying manual 12 is to be selected. To control themain and accompanying organ vibrato, tilt tablets 17 in set 25 areprovided while a further tilt tablet set 26 is provided to selectivelycontrol the status of the foot pedals to a footage of eight or sixteen.Y v

As will be seen infra, each of the tilt tablet sets, except set 23,permits direct coupling of the tones generated to produce the desiredvoices when the appropriate keys on manuals II and v12 are activated.Tilt tablet set 23, however, functions with the instrumentation presetbuttons Id to control the activation of electric lamp tone generatorcircuits of the type described in the co-pending application of RichardE. Williams, entitled Photoelectric Organ, `filed August 5, 1958,assigned to the same assignee as the present application and bearingSerial Number 753,354. Activation of one of the preset buttons 1dselectively permits the activation of certain lamp circuits to providethe desired tonal effect when the keys on manual I1 are struck. It ispossible, however, by the use of tilt tablet set 23 to selectivelywithdraw or subtract certain tone colors which would normally beassociated ywith an instrumentation normally obtained by a particularpreset Vbutton activation and to add others.

Reference is now made to FIGURES 3, 4, and 5 of the drawings whichdisclose the general layout of the mechanism of the present invention.The mechanism comprises a switching section which includes a pluralityof parallel bars 54 extending orthogonally to bezel surface I3. Severalof the bars 54 have a separate coupler 53 connected thereto forcontrolling activation of the tone generator switches that are for-medbetween standards 43 and rods 44, see FIGURE 6. The tone generatorswitches are selectively opened and closed through a plurality ofparallel electrically conducting rods 44 which extend parallel to wallI3 throughout the length of the upper manual 11. The rods 54 areconnected via couplers 53 to cause rotation of selected ones of rods 44when the former are translated in response to activation ofinstrumentation selection buttons I4 or tilt tablets 1'7. In proximityto each rod d4 an electrically conducting standard 43 is located and haspositioned at one of its ends a binding post 45, which is adapted to beconnected to a lamp in the tone generator. The other end of standards 45selectively engages rods 44 when a particular key in manual 11 isstruck. Y It is to be noted from FIGURE 4 that each of the keys does nothave a rod 54 associated with it. This is because movement of one of therods 54 results in movement of circuit establishing shafts 44 throughoutthe keyboard so that the tone generators associated with many of thekeys are effected by a single one of the bars 54--being translated. Eachof the keys 35 of upper manual Il is coupled through one of a pluralityof parallel bars 36 aligned and connected to it and one of the bellcranks 38 to circuit closing standards 43 via one of the horizontallyextending rods 42.

To control the translation of rods 54, each of them is connected to oneedge of a card S5, which cards are aligned longitudinally with the axisof its respective shaft 54. The other edge of cards S5 normally abutsatleast one of a plurality of tabs '71 located on stacked horizontallyextending parallel bars 68, the longitudinal axes of which are parallelto wall 13. Located between bars 68 is a deactivating bar 8S which is ofsimilar shape but sass/,ots

functions in an entirely diiferent manner than the activating bars, asseen infra. The entire stacked arrangement of activating anddeactivating bars is packaged in a single unit which is bounded by topand bottom cover members 77 and 78.

The entire bar mechanism is located directly behind wall 13 and extendsto a line midway between the normal unactivated position of cards 55. Itis suspended within the organ by vertically extending posts 91.1 whichare secured to the ends of the top and bottom covers 77 and 78, asillustrated in FIGURE 8. To maintain the horizontally extending bars 68and $5 in alignment, a plurality of vertically extending posts g5 andseparators 96 are provided between top and bottom covers 77 and 7d.

Interspersed between each of the bars 68 and S5 Aand the top and bottomcovers 77 and 73 are separators 96 and pivot ngers75 and S7, whichcontrol movement of bars 68 and 85 as described infra. Also, extensionsprings 73 and 86 which control return of the bars to their initialposition are attached to each of the bars and are securely fastened viabinding posts that are connected between top and bottom plates 77 and7S.

As seen from FIGURE 7 plate 102 supporting the assembly of lamp bindingposts 45 is maintained in position by its kconnection to support 97which is secured to horizontally extending plate 98., FIGURE 3, byscrews 99. At the top and bottom of frame 161 which is secured tosupport 97 are plate 162 for holding lamp terminal binding posts 45 androd 165, respectively. Rod 103 includes a plurality of bores throughwhich the activating rods 54 connected to cards 55 are inserted. At apoint midway between itsends, vertical support 161 is ,secured to'plate164, having a plurality of vertically extending slots, not shown, tomaintain rods 42, which extend through them, aligned.

Reference is again made to FIGURE 3 of the drawings Wherein key 31 oflower manual 12 is connected via a pivot point, not shown, to activatingbar 32 which is part of the key assembly and is connected to bellcrank33 at its lend remote from the key. When key 31 is activated, bellcrank33 is rotated in response to the upward movement of rod 32 so that anelectric circuit is established within switch box 34. `Closure of switch34 couples predetermined accompanying tones generated as described inthe above named co-pending application of Richard E. Williams to theampliiier and speaker of the organ. Key 3,5 of the upper manual isconnected through a similar pivot bar 36 to the arm 37 of bellcrank 3S,as is clearly shown in FIGURE 5. This results in rotation of the otherarm '39 of bellcrank -38 about pivot point 41 so that horizontal bar 42is translated towards the back of the organ. Bar 42 carries transverselythereto in a vertical direction a multiplicity of electricallyconductive wires 43, (six being shown) which are normally maintained outof contact with rotatable rods 44.

When key is activated, rod 42 translates away from wall 13 so thatelectrical conducting paths are selectively established between rods 44and a plurality of lamps connected to terminal posts 45, located at thelower end of wires 43. Electric current is then `applied to onlyselected ones of terminals 45 which have previously been activated toelectrically connect with rods 44 Via rods 42.

As seen in FIGURE 6i, electrically conducting rods 44o and 44b includesubstantiallyvsemicircular, exterior insulating segments 46 andconducting teat-like segments 47, which segments lare located onopposite sides of the rod. In FIGURE 6, rod 44a has been .rotated byactivation of its kpreset mechanism while rod 441; has not been effectedby the preset mechanism. In consequence, an

i electric circuit is establishedl through rods-44rz and 43a to theterminal 45connected to rod 44a, while no circuit is established throughrods 4411 and 4311. Electric power is connected to each of the rods 44at their ends by the electrical connection established through plate 48,FIG- 6 URE 4, which is maintained at a D.C. energization potential. Thecircuit is completed by connecting the other side of the lamps, whichare connected to terminal posts 45 to ground potential.

To selectively control the rotation of rods 44, each of them is providedwith a plurality of radially extending iingers 49, FiGURES 5 and 6. Eachof the fingers 49 engages an aperture 51 in finger 52 of clips 53. Clips53 are securely fastened to horizontal activating rods 54 by means of aspring 55', FIGURE 6a, which is clamped around the circumferential edgesof the rod 54. l

Gne end of each of the rods 54- is connected to a separate activatingcard 55, certain of which are connected to a tilt tablet 17 via arms 56and 57. Arm 56 extends horizontally from card 55 and is connected to theuppermost segment thereof at one end and at its other end to pivot point56 and arm 57. The end of arm 57 remote from pivot point 5S is attachedto the lower end of tilt tablet 17 so that rotation of tilt tablet 17about pivot point 59 results in arml 57 pivoting about pin 58 and thetranslation of arm 56. At the end of tilt tablet 17 remotefrom the endat which arm 57 is connected, over center spring 61 is secured. Theother end of over center spring 61 is iixe-dly secured to terminal post62 so that the tilt tablet when activated at its lower and upper edgesremains in that position to which it is pushed.

Card S5, in addition to being activated by tilt tablet 17, isselectively activated by instrumentation preset'button 14. Button 14 isconnected via rod 63, which is maintained in a constant angular positionby pin 64 and slot 65 in housing 66, to vertically extending activatingshoulders 67', as clearly seen in FIGURE 12.

Each of the bars 63 includes a tab 69 located on its edge in proximityto shoulder 67 and a plurality of tabs 71 which engage the edges ofcards 55 remote from bars 54. Shoulders 67 extend vertically betweencover plates 77 and 78 from the upper to the lower end -of the assemblyto achieve selective engagement with the tabs on bars 63. y

Disposed on one edge at either end of bar 68 are tabs 72, FIGURE 13,each having one end of parallel extending springs 73 connected thereto,the other end of the springs being securely fastened to binding post 74,FIG- URE 4. Rotatably fastened to the yother edge of bar 68 to eitherend thereof at points beyond tab 72, are parallel pivot arms 75 whichare rotatable about pivot points 76. Rotation of arm 75 relative to thelongitudinal axis of bar 68 is accomplished by the cylinder 70 at theend of 'arm75 which rotates in socket 80 formed at the end of bar 6d.When bar 68 isy in its unactivated position, each of the cards 'whichengage tabs 71 is located at the extreme right side of its respectivetab when viewed from the top.

In response to movement of one of the tabs 69 on the forward edge of bar68 by activation of shoulder 67, iinger 75 rotates about pivot point 76causing bar 68 to move in arearward and sideward direction. Inconsequence, spring '7,3 is tensioned, and cards 55 are translated tothe right, as viewed in FIGURES 5, l2, and 13. At the same time tabs 71move transversely to the direction of cards 55 since the cards aremaintained in a constant transverse position due to their engagement intheV grooves in the top and bottom covers 77 and 7 8 of the stacked barmechanism. vIt has been found that this activating mechtanism producesuniform movement of cards 55 throughout the entire length of bars 68with a minimum of niechanical force, no matter which of the tabs 69 onany bar is activated. Thus, activation of preset button 14 results inthe translation of a plurality of selected activating bars 54 whichcontrol the relative position of the insulating and conducting segmentsof rods 44 and in response to a preselected activation of one of thekeys in upper manual 11, the desired circuits are established throughterminal While I have described' and illustrated one speciiic embodimentof my invention, it will be clear that variations of the details ofconstruction which are specic'ally illustrated andl described may berestored to without departing from the ti'ue spirit and scope of theinvention` asdencd in the appended claims.
